LAMBERT I-LAAS, OF VIENNA, AUSTRIA-HUNGARY, ASSIGNOR TO FRITZ GEBAUER,OF BERLIN, GERMANY.

CALENDER FOR DYEING, STARCI-IING, AND MERGERIZING MACHINES.

To all whom it may concern Be it known that I, LAMBERT Haas, a subjectof the Emperor of Austria-Hungary, and resident of Vienna,Austria-Hungary, have invented new and useful Improvements in Calendersfor Dyeing, Starching, and Meroerizing Machines, of which the followingis a specification.

In the textile industry for the purpose of finishing, starching, dyeing,mercerizing and the like, the textile fabric is often treated byrollers. The arrangement of rollers shown herein obviates certain faultswhich are experienced in the use of roller arrangements hitherto in use.These faults and the removal thereof by the new roller arrangement aredescribed hereinafter with reference to calenders, since the mentionedfaults are found more or less in dyeing, starching and mercerizingmachines.

The calenders used in the textile industry have a number of cylindricalrollers which are placed horizontal and parallel either one above theother or in a horizontal series. Also calenders with a pair of conicalrollers are used, one of which, at least, is engraved. These calendersserve for finishing and brighting fabrics and paper, and if one of therollers is engraved, they serve for stamping ornaments into said fabricsor paper. When the finishing or brighting process is to be carried sofar that the cotton or linen fabric receives a silk-like brightness,these friction calenders have not been satisfactory and the so-calledbeetle stamping calenders had to be used. If the roller arrangement isused in a calender, with the same calender difierent effects may beproduced for the production of which difierent machines have beennecessary heretofore.

By the use of calenders with conical rollers placed complementarily toeach other, it is possible to arrange a cylindrical roller between eachpair of conical rollers, and the conical rollers may even be engraved.

An embodiment of my invention is shown in the accompanying drawing inwhich a pair of conical rollers in contact with a cylindrical roller isshown.

Figure 1 is a side elevation. Fig. 2 shows a vertical section on lineA-B of Fig. 1.

With reference to the drawings, a designates the cylindrical roller, andb and a des- Specification of Letters Patent.

ignate the pair of parallel conical rollers having their small endsdisposed in opposite directions. All these rollers are kept in position,as usual, by a suitable frame d. The cylindrical roller a is driven bymeans of a pulley e or in any other suitable way. But the drive may alsobe effected by driving one of the conical rollers. The fabric f to betreated is guided in contact with the rollers in the direction indicatedby the arrow-head.

By the provision of the cylindrical roller a, between thecomplementarily arranged conical rollers b, c it is possible toproducenon-distorted goods, which was not possible heretofore with thewell-known roller arrangements. By the new arrangement the fabric moveswith the same side in contact with rollers of difierent diameters atdiflerent places, and by the friction rising therefrom, the wholesurface of the fabric is treated by equal frictional action, whereby onthe whole surface an equal effect is produced.

IVith the new roller arrangement, now by a single set of calenders allthose effects may be produced for which heretofore different machineshave been necessary, such as rolling and friction water-calenders orbeetle calenders.

In order to change the effects with the new roller arrangement, it isonly necessary to modify the manner of working by the employment ofrollers of a larger or smaller diameter, or by the use of one-sidedpressure on the fabrics passing between said rollers.

The cylindrical roller a is made of steel, and is engraved or not, andthe same may be provided with a heating device. The conical rollers aremade substantially in the well-known manner, of paper, fabric, or thelike. The amount of taper of the conical rollers is generally slight,the amount of taper depending somewhat upon the pressure to be usedthereon.

Having now described the nature of my invent-ion, what I claim is:

1. In an arrangement of rollers of calenders, machines for dyeing,starching, mercerizing, and the like, the combination of a pair ofparallel conical rollers having their smaller ends disposed in oppositedirections, means provided with a cylindrical surface in contact withboth of said rollers as and for the purpose specified, and means for forthe purpose specified, and means for rocausing motion to be imparted tothe rollers. t-at-ing one of the rollers. 10
